Universal Serial Bus Module (USB)
11.5.1.1 Sync Pattern
Technical Data
170
Each USB transaction is comprised of a series of packets. The USB
module supports the packet types shown in
are generated by the USB host and decoded by the USB device. Data
and handshake packets are both decoded and generated by the USB
device, depending on the type of transaction.
The following sections detail each segment used to form a complete
USB transaction.
The NRZI bit pattern shown in
pattern and is prefixed to each packet. This pattern is equivalent to a
data pattern of seven 0s followed by a 1 ($80).
